Component including internal combustion engine

Technical field

The present invention relates to a kind of component, it includes internal combustion engine, the flywheel being arranged at I. C. engine crankshaft, is arranged in flywheel Starter generator (Startergenerator) in case and the friction clutch that flywheel is connected with speed changer (Reibkupplung)。

The content of the invention

Present invention aim at the power train for improving the internal combustion engine that a kind of utilization starter generator works, wherein, although Starter generator is arranged in the region between flywheel and friction clutch, and whole part has at least less in the axial direction Size.Additionally, the purpose of the present invention is, by the manufacture of the assembling capacity of whole part and each component be kept as far as possible into This is favourable.The present invention is another object is that make it possible module solution (Baukastenloesung) so that different changes Fast device type (manually or automatically speed changer) or transmission interface may be mounted at flywheel of the invention.

It is considered as core of the invention, middleware (Zwischenstueck) is fixed with the outlet side of flywheel, this Sample causes the fixed part (Befestigung) of transmission torque of the middleware at flywheel on the radial direction with the rotation axis of flywheel The fixed part of transmission torque of the spacing relative to middleware at friction clutch is diametrically arranged and middle interiorly Part has the seating plane (Widerlagerflaeche) of the bearing to the friction facing (Reibbelag) of friction clutch.Therefore The radial direction of flywheel/middleware fixed part is smaller than the radial direction spacing of middleware/friction clutch fixed part.Middleware/friction Therefore clutch fixed part is diametrically arranged relative to flywheel/middleware fixed part in other places.

The starter generator for referring to generally can be regarded as motor, and it at least has generator function and therefore will can pass The torque existed in dynamic system is converted into electric energy in the generator operation stage.Additionally, starter generator is at least in internal combustion engine The element (starter function) that certain operation phase is alternatively arranged as being placed in bent axle in rotary motion works.By in setting Between part (on the other hand on the one hand it releasably fix at flywheel at friction clutch), obtain a kind of structure small With the solution of the cost advantages in terms of part realizing necessary function.The favourable manufacture of cost of implementation can thus be carried out, i.e., Seating plane (friction facing to recline be used for thereon and transmits torque) to friction clutch is arranged on intermediary element.In particular, Connection diametrically outside between middleware and friction clutch and the simultaneously fixed part of middleware and flywheel to this Diametrically equally make it possible the small and compact transmission unit of structure in interior placement.

In a preferred form of implementation, starter motor has stator and rotor, wherein, stator is at least partially At the flywheel casing at least partially surrounding (umhausend) flywheel and/or partly in overlap joint friction clutch Fixed at case.Because the supporting fixed part of stator is associated with flywheel casing and/or friction clutch case, especially can be Realize that component is reduced in integrated design.

Additionally, when the rotor of starter motor is at least partially on flywheel and/or at least partially on middleware It is favourable when fixed.Such fixation is fixed including rotor elements relative to flywheel and relative to the anti-torsion of middleware.Though So rotor is moved together with flywheel all the time in such design, but the permanent rotor for driving together is permitted in power train Perhaps starter generator is integrated in the spatially compact technical solution within the power train of internal combustion engine.

Rotor herein shape-ordinatedly and/or power cooperation ground by the adjacent area of flywheel and middleware at least axially Mobility on be restricted.Form fit or power cooperation connection is preferably done so for rotor so that it is final Can not implement to be axially moved in confined state.The connection of the form fit of rotor for example can be by flywheel and middleware at rotor Two side contacts realize.The connection of power cooperation can be implemented by clamping rotor between the region of flywheel and middleware. Rotor can be ensured relative to winged by rotor and flywheel and/or with form fit and/or power cooperation the connection of middleware Take turns and/or relative to the anti-torsion of middleware.Such anti-torsion for example can be by crimping or other types of power cooperation Connect and realize.The corresponding recess of rotor can be for example joined in final confined state in the region of the projection of this middleware In and rotor prevented relative to middleware and the final torsion also relative to flywheel by the form fit.In a preferred implementation Rotor disk shape ground, prism-shaped ground or column ground are constructed in form, wherein, form fit and/or power cooperation engagement or It is carried at the side of rotor and realizes.

Constructed and wherein to middleware plate-like ground, column ground and/or prism-shaped in another favourable form of implementation The heart has the housing region of transmission shaft element.Housing region rotatable movement ground supporting transmission shaft element, but cause in addition true Protect transmission shaft element support diametrically.For example can in housing region shape-ordinatedly and/or power cooperation be disposed with ball The bearing body (Lagerkoerper) of bearing or other forms.The receiving of ball bearing press-in annular in preferred form of implementation In region.When especially being constructed in middleware plate-like, when housing region include flange intercept (Kragenabschnitt) (its Refer to liftoff orientation from flywheel in assembled state) when, it is favourable.The face that the flange intercept provides increase is used for consolidating for bearing body It is fixed.

Additionally, when middleware has at least one centering joint element in assembled state towards the face of flywheel, (it connects In closing the centering complementary elements (Zentriergegenelement) of flywheel side) when, it was demonstrated that for favourable.By such use The diameter parallel tolerated and/or the position of the two elements are for example can ensure that in the centering device of the connection of flywheel and middleware Put orientation and also ensure that the main body for treating to be connected with these elements.Therefore less chain is realized via multiple components laid each other Tolerance, i.e. less cumulative single tolerance.Here, centering joint element can for example be configured to annular protrusion (Ringwulst) Or it is configured to be arranged in the protuberance (Hervorhebung) on annulus and complementary elements of feeling relieved are configured to and annular protrusion or cloth Put the corresponding face intercept (Flaechenabschnitt) of protuberance on annulus.

Another advantageous measures are arranged to, for middleware is corresponding with the spacing of rotation axis to the fixture that flywheel is fixed In 0.3 to 0.7 times, preferably 0.4 to 0.6 times of the spacing of the fixture for middleware and clutch case to be fixed.Therefore For the fixture of fixing middleware and flywheel on the one hand relative to the fixation for middleware and friction clutch to be fixed Part is arranged interiorly relatively.Because the two fixtures relatively with rotation axis separately, are on the one hand used with the relation In by middleware and the fixture that clutch is fixed relative far can arrange outside and realize simultaneously fixture it is favourable, this Sample fixation sufficiently with rotation axis separately so that in addition the quality of the fixture pro (quality increase) act on it is winged The flywheel mass of wheel.Additionally, realizing that effective intensity and/or rigidity are improved by the Quality advance away from line.

Here, when the spacing of rotor and rotation axis is corresponding to the fixture for middleware and flywheel to be fixed and rotation In addition it is favourable at 1.05 to 1.40 times of the spacing of axis.Thus be accordingly used in the fixture phase that middleware is fixed with flywheel Further arrange and maximum arranged with its spacing with what is limited simultaneously interiorly for rotor.Herein propose, it is fixed Part directly engages or is penetrated into the material of rotor and/or fixture is directly joined to the carrying rotor of intermediary element In region or through itself or and/or be directly joined to flywheel carrying rotor region in or through its.Because The component of the fixture for middleware and flywheel to be fixed is arranged in " near zone " of rotor, middleware or flywheel The region of carrying rotor for example can simultaneously provide the receiving function for the fixture being fixed on middleware at flywheel.
